Prefabricated assembly type construction method for underground subway station in soft soil area
The invention relates to a prefabricated assembly type construction method for an underground subway station in a soft soil area, and is applied to the field of subway construction. The construction method comprises the steps of end well construction, specifically, an end well is constructed preferentially for construction equipment to enter a standard section for construction; a preparation step: constructing the underground diaphragm wall in the delimited area to form a construction area; in the foundation pit construction step, a foundation pit is excavated in a construction area, and a supporting set is adopted for supporting; a bottom plate construction step: forming a bottom plate of the station at the bottom of the foundation pit, and after hardening, pouring a lower side wall to the lower end face of the nearest support to make up a construction area; a middle plate component construction step: assembling a middle longitudinal beam and a middle stand column, and assembling on a middle plate along the height direction of the underground diaphragm wall to form an upper side wall; a top plate component construction step: assembling an upper longitudinal beam and an upper stand column on the middle plate, and fixing one end of the upper longitudinal beam with the middle plate; and a support dismounting step: dismounting the support group and the inclined support, and carrying out soil covering and backfilling. The construction method has the advantages that the reserved construction area is large, and construction is more convenient.
本申请涉及一种软土地区地下地铁车站的预制装配式施工方法,应用在地铁施工的领域。其包括端头井施工步骤,优先施作端头井供施工器械进入标准段进行施工;准备步骤,在划定区域施工地下连续墙,形成施工区域;基坑施工步骤,在施工区域开挖基坑,采用支撑组进行支撑;底板施工步骤,在基坑底部形成车站的底板,硬化后浇筑下侧墙浇筑到最近支撑的下端面让出施工区域;中板构件施工步骤,拼装中纵梁与中立柱,并在中板上沿地下连续墙的高度方向拼装形成上侧墙;顶板构件施工步骤,中板上拼装上纵梁与上立柱,并将上纵梁的一端与中板固定;支撑拆除步骤,拆支撑组与斜撑,并进行覆土回填。本申请具有预留施工区域大,施工更加方便的效果。
